WRW4, a specific formyl peptide receptor-like 1 (FPRL1) antagonist, inhibits WKYMVm binding to FPRL1 with an IC50 of 0.23 μM. WRW4 specifically inhibits the increase in intracellular calcium by the FPRL1 agonists MMK-1, amyloid beta42 (Abeta42) peptide, and F peptide.

How to use

In Vitro:

WRW4 inhibits Abeta42 peptide-induced superoxide generation and chemotactic migration of neutrophils, and also completely inhibits the internalization of Abeta42 peptide in human macrophages. WRW4 specifically blocks ERK phosphorylation downstream of FPRL1 by WKYMVm.
